More than a dozen different fires are burning across eight counties since Sunday night, while over 20,000 people in the paths have evacuated, more than 100 people are also still missing, fire officials said.

More than 100 phone calls have been made to Sonoma County's missing person hotline, though they did say that some calls may be duplicates, but that increased resources are headed to the region on Tuesday to continue fighting against the blazes.

"Hopefully we'll start seeing some turnaround throughout the course of today and into tomorrow," Scott McLean, deputy chief of the California Department of Forestry and Fire Protection, or Cal Fire, said on the Today Show.

Gov. Jerry Brown declared an emergency in the affected counties, which includes Napa and Sonoma, and the Federal Emergency Management Agency also agreed to the state's request for federal funding to help extinguish and recover from the fires, the Department of Homeland Security announced.

Marian Williams from Kenwood in Sonoma County described to an NBC Bay Area affiliate that she and several other neighbors drove through the flames before dawn as the fires reached the area.

"It was an inferno like you've never seen before," Williams told the station.
